e liable to the defect 4that their e'ciency is very l0 restricted, `owing mainly totheir mode of suspension froina strinof.. .y In view of this defect` amode of fitting ofthe end of the string from inconvenience that t eball is never swung 'i270 back towards the boxer after a blow, and that the boxer, before aiminga finth'er blow fat the ball, must `alvvays fetch` itV backfirst. l ,y

Y All, the, imperfections described aboveare now ,completely eliminated bg'the present in! ball striking thewalls or the furniture. :The baclrand forward motions of the ball, and all Y its other motions, are intensifiedptothe greatest extent, thus ena-bling the man toad#4 just his tactics to special intricacies, orto assumed physical advantages or disadvantages of an opponent. The said invention f possesses a further advantage in thatit can be employed in any room, even in a bedroom or a dining-room, and that it can be removed after use, so as not to detract from the appearance of such places.
